GIG-SADDLE-TREE.

Specification of Letters Patent.

Patented J an. 25, 1916.

Application filed December 27, 1913. Serial No. 809,044.

To all whom it may concern Be it known that I, ALEXANDER Mo- Knxzin, asubject of the King of Great Britain, residing at Kippen, in theProvince of Ontario and Dominion of Canada, have invented certain newand useful Improvements in Gig-Saddle-Trees, of which the following is aspecification.

This invention relates to a gig saddle tree, and the principal object ofthe invention is to provide a device of the character described which isso constructed that the hook may be easily removed from the base plateand a new hook provided in case the original hook is broken.

Another object of the invention is to so. construct the device that whenthe hook is in place it will be very securely held in place andprevented from working loose.

Another object of the invention is to so construct the device that itmay be very cheaply made and very easily and quickly put together andtaken to pieces.

This invention is illustrated in the accompanying drawings.

Figure 1 is a perspective view of one form of the gig saddle tree; Fig.2 is a view taken along the line 22 of Fig. 3; Fig. 3 is a sectionalview taken along the line 33 of Fig. 2; Fig. 4 is a perspective View ofa modified form of the gig saddle tree; Fig. 5 is a view taken along theline 5-5 of Fig. 6; Fig. 6 is a sectional view taken along the line 66of Fig. 5.

The form shown in Figs. 1, 2, and 3 coinprises a base plate 10, a hook11, and a securing plate 12. The base plate 10 is provided at a pointintermediate its width with enlargements 13 which extend from theforward edge of the base plate to a point adjacent the center thereofand form the side walls of an undercut seat 1 1. This seat 14 is taperedlongitudinallv and the side walls gradually decrease in height from theforward edge of the base plate to the inlet end of the seat where theside walls merge into the upper face of the base plate. Thisconstruction is very clearly shown in Figs. 2 and The hook 11 has itsbase portion formed into an enlarged wedge-shaped foot 15 which isclove-tailed in cross section and fits into the seat 14. When this foot15 is placed in the seat 14 and moved forwardly, the foot will wedge inthe seat and thus be prevented from passing out through the constrictedouter end of the seat. The securing plate 12 is curved in cross sectionso that it overhangs the enlargements 13 when in place, and is providedupon its end face with a dove-tailed block 16, which block fits withinthe inner end portion of the seat 1% as shown in Figs. 2 and 3 and bearsagainst the inner end of the enlarged foot 15 and prevents the foot frommoving rearwardly in the seat when the securing plate has been connectedwith the base plate by means of the screw or bolt 17.

When this gig saddle tree is in use, it is assembled as shown in Fig. 1and will be very serviceable due to the fact that the hook 11 will berigidly secured to the base plate and therefore can not work loose andturn upon the plate. If the hook becomes broken, or if it is desired toreplace the hook with a hook having a modified form of bill, it issimply necessary to remove the screw 17 and the securing plate 12 canthen be removed by sliding the block 16 rearwardly out of the seat 14.The broken hook can then be removed by sliding the hook rearwardly and anew hook could then be put in place and secured in the seat by replacing the securing plate 12.

In Figs. 1, 5, and 6 there has been shown a modified form of the gigsaddle tree. In this form the base plate 18 is provided with an enlargedcentral portion in which there is formed an undercut tapered slot 19 provided with an enlarged inner end portion 20. The hook 21 which is usedin connection with the base plate 18 is provided with a wedge-shapedbase :22 which has its rear portion flared transversely a greater extentthan its forward end portion so that the hook will be tilted slightlywhen placing the base in the slot 19. After the base has been moved intothe slot a suflicient distance, its rear end portion can be dropped intothe enlarged-end portion 20 of the slot and the hook then moved to theposition shown in Figs. 4 and 6 thus causing the base to be tightlywedged in the slot 19 as shown in Fig. 5. The uppenend portion of thishook is formed into the neck 23 and finger 24, the neck 23 carrying ahead 25 which overhangs the upper end of the finger 24. The securingplate 26 is curved in cross sec tion so that it will overhang the wallsof the slot or seat 19 and is provided with an opening through which thehook passes. After the book has been put in place, the securing plate isthen put in place with the hook passing through the opening27 and theplate is then secured to the base plate 18 by means of the screw 28.WVith this form the hook may be detached from the base plate 18 asreadily as the hook 11 may be detached from the base plate 10. It issimply necessary to remove the screw 28 and the securing plate can thenbe removed from the base plate and the hook removed from the seat 19. Itwill thus be seen that What is claimed is:

A gig saddle tree comprising a base plate provided With a taperedundercut slot terminating at its rear end in an enlarged pocket, a hookhaving a Wedge-shaped base havingside surfaces normal to said base plateengaged in said slot, and a securing plate having an opening closelyfitting said Wedge-shaped base to hold the hook in position.

In testimony whereof I affix my signature in presence of tWo wltnesses.
